ROAD- GRADER.

Patented Au 16, 1910.

and across the path traveled by the same.

To on whom it may concern:

' Be it known that I, OnnAnmmw Nsss,

.a citizen of the United States, and a resident of 'Zumbrota in thecounty of Good hue and State of Minnesota, have invented a, certain newand useful Road-Grader, of which the following is a full, clear, andexact description.

The principal objects which the. present invention has in view are: toprovide a machine whei'cin a road bed may be leveled and rolledsimultaneously; to provide, a mechanism wherein the excess materialconstituting the surface is conveyed to, and deposited in the path of aressure roller; to provide a mechanism of t e character mentioned, thearea of o eration of which may be varied at will; and to provide amechanism for manipulating the various parts constituting the grader,

One embodiment of the present invention is disclosed in the constructionillustrated in the accompanying drawings,

wherein like characters of reference indicate corresponding parts In allthe views.

Figure 1 1s a plan view of a grader constructed in conformity with myinvention; Fig. 2 is a sectional rear view of the grader wings, taken onthe line 22 in Fig. 1; Fig. 3 is a plan view of the platform and devicefor manipulating the grader wings; Fig. 4: is a longitudinal sectionalelevation taken on the line 4.4 in Fig. 1; Fig. 5 is a 4 view similar toFig. 4, showing the forward end of the grader wings raised from surfacecontact with the ground; and Fig. 6 is a view similar to Figs. 4 and 5,showing the grader wings completely raised from surace contact with theground.

The body of the machine is carried u ion a roller 7 and a forward casterwheel 8. The frame com rises principally side bars 9 upon which t cbrackets 10 carrying the journals for the axle ll of the roller 7 aremounted. At the rear the side bars 9 are conhected b a cross brace 12,while at the front the side bars t) are converged, and bolted to a post13 in which the pivot mounting of the caster wheel. 8 is formed.

The roller 7 is of any desired construction and is provided with ascraper 14 susnded from the brace 12 by springs 15.

The side bars 9 are braced forward of the extends in line with the axleof the roller 7 This leveler operates to more evenlyv dis tribute suchdirt as is delivered in the path of the roller 7 by the grader win s,hereinafter described. The leveler is raced by arms 18 which are mountedupon the side bars 9.

The leveler is raised from the ground by means of a bell crank lever 19,mounted.

upon the rod 16. The lever 19 is connected tothe leveler 17 by a liftinrod 20 and to a lever 21 by a connecting rod 22. The lever j 21 is heldin position by a hand grip detent 23, which plays in the teeth of atoothed quadrant 24 secured upon the side bars 99.

The platform 25 is constructed of any suitable material, and ispreferably in the shape shown in Figs. 1 and 3 of the drawings. The purose of the platform is to provide a stan ver 21 and hand wheels 2626 and27 and 28.

for the driver of the ma-' chine, and to furnish mountings for the le-'80 The grader wings above mentioned aresimilar-in construction on bothsides of the center of the machine, but for the c0nven ience ofdescription, one only will be de; scribed, the designating letters beingduplicated on both constructions. The two pairs; wings are connected attheir rearward ends by a connecting bar 29, to which they are joined bymeans of cars 30, which are perforated to register with perforations 31formed in the said connecting bar. When so registered, a cotter 01'other suitable pin is driven through the ahned perforations,

and the lateral adjustnient of the wings beconic fixed. The rod 29 issteadied and maintained in position by a brace 32, which is suitablypivoted to the said rod and to one of the side bars 9, .9. Thisconstruction permits the rise and fall of the rod 29 but maintains thesaid rod in its lateral location;

V The wings are suspended at the rear end 37 from'the ratchet'36, thepost 35 may be rotated to lower or raise the rear ends of the graderwings, as desired.

The forward end of the win 5 is carried u on caster wheels 38, mounteupon suit- 1e spindles 39 which are seated in suitable vertical bearingsset in the carryin truck bars 40. Each truck bar 40 is brace in relationto the grader wings by a rod 41,

which is pivotally mounted at 42 on the rearmostgrader wing The graderwings 43 are formed as elongated scoops or grading shovels, and arebraced in their parallel 45, to which a bell crank 46 is connected.

The bell crank 46 is pivotally mounted on the truck bar 40, and theupper. end is connected with a pull rod 47, engaged by a chain 48, whichis adapted to be wound upon a spool 49 on a post 50. The post 50 isprovided with a ratchet 51 and a pawl 52, to hold the said 0st inposition when the chain 48 is wound post 50 carries the wheel 26 and isrotated thereby.

When the post 50 is rotated to wind the chain 48, the bell crank lever46 is rocked to raise the outwardly extended arm connected by the liftinrod with a cross brace 53 connecting the parallel wings 43. The wheels38 remaining on the ground, the height of the truck bars 40 is.unchanged, while the bell crank 46 being moved as above described,raises the outer or forward ends of the grader wings from contact withthe ground. With a lifting arrangement such as above described, thegrader wings are lifted at either end, or at both ends, by

rotating the posts and 50, these osts be- .ing rotated by means of thehand w eels'26,

26 and 28, as shown in the drawings.

The pairs of grader wings are arranged to be set at angles widel oracutely divergent, and it is to regu ate the outward spread ofthesegrader wings, that I have provided adjusting racks 54. These racks areperforated as shown in Fig. 1 of the drawings, to receive a hooked endof pull rods 55, which are provided with eyelets at the forward end toreceive a ring 56'. As the rods 55 are connected with the variousperforations in the racks 54, it will be seen that the outward extensionof the wings 43 is limited to the spread of the rods 55. For instance,if the rods 55 are connected, as shown in Fig. 1 of the drawings, withthe racks 54, the wings are in position to spread upon the spool 49. The

to their extreme capacity. Shouldthe hooks in the ends of the rods 55 benow transferred to the perforations in the extreme forward ends of theracks, it will be seen that the extent of the spread of the wings 43 islimited over that shown in the former position. As an adjunct to therods 55 there are provided connccting, chains 57 which are connected topull the ends of the wings 43. The machine is drawn over the roadby ateam, the single tree whereof is connected toa ring 61.

It is to provide means-for spreading or contracting the wings 43 duringthe regress of the machine that I employ a ciain 62. The chain 62isextended on both sides of the caster wheel 8 and is guided by sheaves 63at this 'point. Between the sheaves 63 and a spool 64 upon which bothextensions of the chain are wound, are sheaves ,65. The spool 64 isfixedly mounted upon a post 66 which is controlled by the hand wheel 27.

This post, like those heretofore mentioned, is

controlled by a ratchet 67 and pawl 68. The outer ends of the chain 62are secured to the link 60 to which are likewise secured the draft teamand the pull bars 55, 55. When new the'post 66 is manipulated to windthe chain upon the spool 64, the chain 62 and with it the link 60 aredrawn toward the platform 25 of the machine. In thus moving the link 60,the tension upon the chains 57 and the draw rods 55 is released, permitting thc outer ends of the wings 43 to extend farther laterally.There is practically no limit to the lateral extension 'of the wings 43,.although it is designed that the inclination of the same to the lineof'draft shall be such as to deliver the loose or surface dirt into thepath of the roller 7 It will be seen that by the manipulation ofthe handwheel 27, the extension laterally of the wings 43 may be changed withoutstopping oigclianging the speed of the draft team." The position of theconnectin bar 29 relative to the roller 7 is maintained by braces 69,pivoted at 7 0 to the cross brace 12 of the frame of the machine, andalso pivoted at 71 to the connecting bar 29.

The opei;ation,of a machine .constructed' as shown in the accompanyingdrawin s is as follows: When passing to the fiel of operation the wings43 are raised out of contact with the ground. The hand wheel 27 is alsomanipulated to unwind the chains 62, which permits the pull of the teamto draw the wings 43 into close alinement, or

so that the same stand extended in the line of draft. In this positionthe machine does not occupy more space than an' ordinary wagon. Thestructure is supported in this position upon the caster wheels 38, thecaster wheel 8 and the roller 7. Having arrived at the field, ofoperation, the hand wheel 27 is manipulated to wind the chains 62 uponthe spool 64 to draw the link toward the platform 25. If the road to betreated is wide, the extension of the wings 43 is-according to suchwidth. If, for any reason, such as, the interposition ofa metal manholehead, it is desired to raise the one or the other pair ofwings 43, thisis accomplished bymanipulating one or the. other of the wheels 26, toraise the forward ends of the pair of wings desired to b'e lifted.Having passed the obstruction, the wings are dropped to position. If itis desired to contract the wings during the operation, due to acontraction in the road bed, or other cause, this is accomplished byreleasing the hand wheel 27 and permitting the draft chains 62 toextend, so that the chains 57 will draw t'heouter ends of the wings 43toward eac}i",other. The work having been completed, the wings 43 areraised from contact with the ground by the manipulation of the wheels 26and 28, and the outer ends are drawn together by the manipulation of thewheel 27, permitting the draftchains (32 to extend, and the chains 57 todraw the ends of the wings into close re lation.

Having thus described my invention, I

claim as new and desire to secure by Letters Patent:
